Enabling FlexAttach Virtual pWWN

The FlexAttach virtual pWWN feature is enabled automatically, manually, or by mapping pWWN to
virtual pWWN.
Automatically Enabling FlexAttach Virtual pWWN
The virtual pWWN is enabled automatically on all the NPV switches or per port on the NPV box. When
enabled automatically, a virtual WWN is generated from the device switch WWN. This WWN is used
as the virtual pWWN. Virtual pWWNs are generated using the local switch WWNs.
The port must be in a shut state when the virtual pWWN is enabled.
Note
To enable virtual pWWN automatically, perform this task:
